Safety Instructions
B3910-A2-GN32-30 November 1996
Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or
included in the manual.
2. This product is intended to be used with a three-wire grounding type plug – a plug
which has a grounding pin. This is a safety feature. Equipment grounding is vital to
ensure safe operation. Do not defeat the purpose of the grounding type plug by
modifying the plug or using an adaptor.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for
the presence of earth ground. If the receptacle is not properly grounded, the
installation must not continue until a qualified electrician has corrected the problem.
If a three-wire grounding type power source is not available, consult a qualified
electrician to determine another method of grounding the equipment.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable
operation of the product and to protect it from overheating, these slots and openings
must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where
persons will walk on the power cord.
5. Do not attempt to service this product yourself, as opening or removing covers may
expose you to dangerous high voltage points or other risks. Refer all servicing to
qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be
required by the regulatory inspection authority for the installation site, are the
responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable
Safety Standards and regulatory requirements of the country in which it is installed. If
necessary, consult with the appropriate regulatory agencies and inspection
authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two
or more buildings. If products installed in separate buildings are interconnected, the
voltage potential may cause a hazardous condition. Consult a qualified electrical
consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.
In addition, if the equipment is to be used with telecommunications circuits, take the
following precautions:
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed
for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Avoid using a telephone (other than a cordless type) during an electrical storm.
There may be a remote risk of electric shock from lightning.
Do not use the telephone to report a gas leak in the vicinity of the leak.

Overview
The COMSPHERE 391x Series modems, a new generation of full-feature, high-speed modems,
offer reliable asynchronous and synchronous operation over leased-line or dial networks. The 391x
Series modems’ unique software defineability allows for the addition of future enhancements,
whether it is installing new features or firmware upgrades.
The modem’
s compatibility with a number of dialing methods and protocols, such as asynchronous
AT commands, CCITT V
.25bis dialing, and the user
-friendly diagnostic control panel (DCP),
permits the 391x Series modem to be used in a variety of applications and environments while also

.
Automatic and manual backup with standby capabilities for 4-wire/2-wire leased-line
applications. (The backup facility may be either a 2-wire dial line or a 2-wire leased line.)
Multipoint Applications
In multipoint applications, leased-line circuits are used for time sharing the same front-end
processor (FEP) port with multiple remote locations. The FEP (via the control modem) regulates
traffic on the line by continuously polling the tributary DTE(s) in a predefined sequence. Only one
tributary can communicate with the control modem at a given time. Modems configured for Trellis
Multipoint (TMp) cannot be used in a point-to-point, constant carrier application. (Refer to the
Leased Line
section in Chapter 4 for configuration options.)
Leased Backup Applications
In
leased backup applications, a 2-wire leased line is used as the backup facility instead of the
normal 2-wire dial line. Plug the leased line into the jack labeled DIAL on the rear panel of the
modem (see Figure 2-1 in Chapter 2), and enable the Dual_Leased_Ln configuration option. (Refer
to the
Leased Line
section in Chapter 4 for configuration options.) Except for dialing, ring
indication, and call progression functions, you control the backup function as if it were a normal
dial backup.
COMSPHERE 391x Series Models
The 391x Series family is available in two models: the Model 3910, a 4-wire/2-wire standalone
modem, and the Model 391
1, a carrier-mounted version of the standalone unit. Both models offer a
variety of modulation schemes and network enhancements while still providing reliable,
high-speed data transmission using the latest in modem technology
.
